If it helps, it fits 3 Penelope Midis and a fourth if you lay it across the top, so maybe I'd guess it could fit 3 Penelopes? I have one on order but only have Little and Midis to play with...I've been thinking about this bag a lot and trying to compare it to what I have so I can understand the size better without seeing irl. I realized last night that - on paper at least- the height and length are the same a Penelope. So I have one of my Penelope's out and I am constantly looking at it trying to imagine the depth as well. [emoji28]
